| 20090140472 | REDUCTION APPARATUS, REDUCTION APPARATUS MANUFACTURE METHOD, AND VACUUM SMELTING REDUCTION FURNACE USING THE SAME - The invention discloses a reduction apparatus having a main body made of silicon carbide-based material and collectively formed by a top portion, a bottom portion, and a side portion, wherein the bottom portion includes a slanted plane, and the main body has an inlet and a metallic vapor exit provided near the top portion and an outlet provided near the lowest end of the slanted bottom portion; an inlet closure connected with the inlet; an outlet closure connected with the outlet; and a metal collector or a condenser connected with the metallic vapor exit. The invention solved problems found in conventional reduction retorts, including: small capacity, low metal output, inconvenience in charging reactant material and discharging spent residue, and heavy workload for workers. The invention also shortened the time for reduction reaction, increased production efficiency and output of the reduction furnace, and reduced production cost. The invention can be used in production of metal such as magnesium, strontium, zinc, and beryllium by vacuum smelting reduction process. | 06-04-2009 |
